Product Description

Discover the Spherical Control Valves and Ball Valves engineered by SNT Machinery (Qingdao) Co., Ltd., setting a new standard in performance with their Zero-Leakage capabilities. Engineered to thrive in even the most demanding environments, these valves excel in service applications characterized by high temperatures and pressures, ensuring unrivaled reliability and efficiency.
Each valve is meticulously crafted with a ball and seat that have been hard-coated using advanced materials such as chrome carbide or tungsten carbide. This cutting-edge technology provides exceptional resistance to erosion and abrasion, guaranteeing that our products withstand the test of time even under the harshest conditions.
At SNT Machinery, we revolutionize valve technology using the HVOF coating system. Our exclusive mate-lapping technique ensures an impeccable 100% seal, while live loading achieves zero emissions. Ingeniously designed, the ball remains in constant contact with the seat, effectively wiping away contaminants and performing a self-cleaning action. This innovative design not only prevents interference and damage from contaminants but also makes these valves ideally suited for challenging slurry and abrasive services.

 

Our Advantages

Our SNT Ball Valves are meticulously engineered to adhere to a comprehensive array of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This exceptional series finds its applications across a diverse range of industries such as petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations.

Key Features of Our Valves:
Ingenious simplicity in design allows for swift disassembly.
With our dedication to regular maintenance of all valves, our ball valves are crafted to facilitate effortless maintenance featuring a non-tight fit design that significantly reduces servicing time.

State-of-the-art sealing ensures unparalleled security.
The multi-layer composite sealing of the stem and body delivers enhanced double sealing through the harmonious combination of an O-ring and either graphite or PTFE.
Our design impeccably complies with TA-Luft/Shell SPE 77/312 standards.

Exceptional longevity translates to economic efficiency.
For metal sealed ball valves, we utilize cutting-edge processes such as spray welding, spraying, and fusion welding for the ball and seat ring, ensuring a hardness ranging between HRC58-73 and a binding force of 80-40MPa. Impressively, they are capable of more than 100,000 on-off cycles with a leakage class of ANSI VI.
 

Innovative modular design ensures user convenience.
Our modular inner sealing design provides the interchangeability of soft and metal seats, enhancing adaptability.

Diverse connection types ensure optimal user comfort.
We offer a variety of connection types including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, which are globally recognized and facilitate ease of use.

Extensive application experience guarantees reliability.
SNT Valves have established a strong presence in industries such as petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations. We are renowned in the market for providing well-founded solutions tailored to specific service conditions.

 

Structural Features

Engineered with an innovative special packing combination, our valves are designed to fulfill the stringent emission requirements of 100 ppm. This sophisticated feature effectively reduces stem friction by an impressive 20%, ensuring optimum performance.

1. Our robust anti-blowout design provides enhanced safety by preventing the stem from being expelled, thereby averting potential damage and ensuring operational integrity.

2. The advanced seat ring structure, incorporating a wave spring and dual-scraper mechanism, meticulously cleans the ball surface, maintaining an impeccable seal and ensuring flawless functionality.

3. With our dual-sealing technology, we assure an exceptional leakage class by ingeniously preventing flow contact with the spring, thus enhancing seal reliability and durability.

4. Our valves boast a soft seat sealing performance that is both stable and reliable, offering unparalleled assurance of sealing integrity under various conditions.

5. Featuring a sophisticated design for draining and sweeping, our valves effectively prevent jamming, ensuring seamless operation by maintaining cleanliness throughout usage.

6. Compliant with the rigorous API 607 standards, our valves are equipped with fire-proof and anti-static functions, delivering superior safety and unmatched reliability in demanding environments.
